This book is based on my doctoral thesis at the Helsinki University of Technology. Several different projects during five years guided me from the basics of the RF IC design to the implementations of highly integrated radio receiver chips. Sharing time and effort between IC and system issues is not always straightforward. I have been lucky to follow both topics and share experiences with diligent and enthusiastic people having different specialities. As a result, this book will cover a wide range of different topics needed in the design of highly integrated radio receivers. Experiences from the first receiver prototypes for the third generation cellular systems form the basis of this book. Most of the issues are directly related to the early proposals of European and Japanese standardization organizations. For example, the chip rate was originally set to 4. 096 Mcps in a wide-band CDMA channel. I have kept that number in the book in most of the examples although it has been later changed to 3. 84 Mcps. I hope that the readers will accept that and the possible other incompabilities to the latest specifications. At least in the research phase the changes even in the most essential requirements are definitely not a rare incident and IC designers should be able to react and modify their designs as soon as they can.

Urban activism can manifest in many guises, from community gardening to mass naked bike rides. But how might we theorize the evidence of the collisions between social forces that take place in our streets and public commons? Cities are formed through these collective collisions in time.

Free Download Direct and Large-eddy Simulation by Bernard J. Geurts
English | July 15, 2022 | ISBN: 3110516217 | 312 pages | MOBI | 6.17 Mb
The series is devoted to the publication of high-level monographs and specialized graduate texts which cover the modern mathematical foundations behind computational science and its applications in physical and life sciences, and in engineering. One of its main objectives is to make available to the professional community expositions of results and in-depth presentation of techniques that are of current importance to technological and practical applications. This authoritative book presents an overview of the mathematics behind the simulation of turbulent flows and discusses in detail the phenomenology of turbulence in fluid dynamics, direct and large-eddy simulations, subgrid modeling, and also covers validation and reliability issues.

Reducing Race Differences in Direct-to-Consumer Pharmaceutical Advertising The Case for Regulation

Free Download Stephany De Scisciolo, "Reducing Race Differences in Direct-to-Consumer Pharmaceutical Advertising: The Case for Regulation"
English | ISBN: 1498574165 | 2018 | 140 pages | EPUB | 5 MB
Reducing health disparities by increasing access to health information is a national health policy priority. Evidence exists that direct-to-consumer pharmaceutical advertising (DTCA) is effective in educating consumers about health issues. However, racial disparities exist in such advertising. In 2009, the Food and Drug Administration (FDA) issued a report that included recommendations for enhancing the ability of DTCA to reach disadvantaged populations, including racial and ethnic minorities. Reducing Race Differences in Direct to Consumer Pharmaceutical Advertising compares the pharmaceutical advertisements placed in five popular women’s magazines published prior to and following the 2009 FDA report to assess the impact of these recommendations on the content and appearance of advertisements placed in magazines of differing racial orientation. From a health policy perspective, the results are disappointing. The FDA recommendations had no impact on the frequency or content of the DTCA appearing in White-oriented versus Black-oriented magazines. In fact, far fewer drugs used to treat life-threatening conditions were advertised in Black-oriented magazines after the 2009 FDA recommendations. The book concludes that enhancing the educational and motivational value of DTCA will require more than a set of recommendations. The results shed light on the pharmaceutical industry’s compliance with both hard and soft regulation. Neither federal recommendations nor industry guidelines resulted in the changes to DTCA envisioned by the FDA. Regulatory action is necessary to ensure that pharmaceutical companies develop advertising campaigns that not only promote their products, but also positively impact the health outcomes of those who read their ads.

Free Download Direct Nerve Stimulation for Induction of Sensation and Treatment of Phantom Limb Pain by Winnie Jensen
English | PDF (True) | 2019 | 302 Pages | ISBN : 877022076X | 94.6 MB
The amputation of a limb is a surgical intervention used as a last resort to remove irreparably damaged, diseased, or congenitally malformed limbs where retention of the limb is a threat to the well-being of the individual. The procedure traumatically alters the body image, but often leaves sensations that refer to the missing body part, the phantom limb. In 50-80% of cases, these sensations are perceived as painful and referred to as ‘Phantom Limb Pain’.
